Description

[Detailed explanation of the invention] This invention provides a ceiling rail and a floor rail at any location in the room, and a foldable door is built between these rails, making it convenient to easily divide the room into a study room or storage space. Regarding a folding door device.

Various types of folding door devices have been proposed and put into practical use.

However, although these conventional devices have no problems with the ceiling rails and floor rails, various problems have been raised regarding the structure when installing folding doors.

The main problem is that the mounting structure of the pivot pins that support the door at the top and bottom of one end of the folding door and allow it to rotate, or the guide pins that guide the movement of the door along the rails, is not connected to the door. Because it is a one-piece structure, it is impossible or complicated to change specifications for left-hand or right-hand when installing a folding door, or it is a composite structure to support the pin in a fixed position against the elasticity of the spring. The resin support piece easily comes off and gets lost.

The problems mentioned above are due to the structure in which the pivot pin or guide pin is integrated into the folding door.
Alternatively, the pin may be supported by a small support piece that is easily lost or forgotten.

The present invention solves the above-mentioned drawbacks, and its structural feature is that the upper and lower frames that make up the folding door body are provided with mounting parts of a common shape for mounting pivot pins or guide pins. The folding door, pivot pin, and guide pin are provided separately from the folding door.
Attach to the upper and lower frames when actually installing the folding door during construction.

Therefore, the pivot pin and guide pin used here are different in shape and structure from conventional ones.

Among them, the guide pin is the most distinctive.

That is, a temporary fixing pin is provided on the pin, a spring is further inserted onto the pin to elastically support the pin, and the temporary fixing pin is engaged with a temporary fixing pin locking piece provided on the side of the pivot pin body. When in use, the temporary fixing pin is released from the pin fixing piece by only slightly turning the pin, and the pin protrudes under the force of the spring and fits into the pin hole provided in the rail.

This will be explained in detail below with reference to the drawings.

The drawings are illustrative of the present invention, and Fig. 1 is a front view of the folding door device of the invention, Fig. 2 is a perspective view of a portion corresponding to section A in Fig. 1, and Fig. 3 is a pivot pin. shows a side view.

FIG. 4 is a perspective view of a portion corresponding to section B in FIG.
FIG. 5 shows a side view of the guide pin.

As shown in Figure 1, a folding door device usually has a ceiling rail 1 and a floor rail 2 installed at any location in the room, and two door panels 3 are hinged between the rails 1 and 2 with a hinge 4. This is a folding door, and one side of this folding door is placed up and down (A and B in the diagram).
Pivot pins 5 and 6 are provided on the rails 1 and 6 to rotatably support the rails 1,
The two spaces can be slid open and closed, and if the room is large, the remaining part may be shielded with a wall plate 9.

Usually the upper and lower pivot pins are also upper and lower guide pins are also door plate 3.
, 3 is commercially available.

By the way, in the present invention, as shown in FIGS. 2 to 5, neither the pivot pin nor the guide pin are integrated with the door plate 3, but are provided as separate parts.

That is, as a product, the upper frame 10 and lower frame 11 of the door plate 3 are only provided with pin mounting portions 12 for a pivot pin and a guide pin, respectively.

Here, the pin attachment portion 12 is a square hole 13 for inserting a pivot pin or a guide pin and a round hole 15 for passing a pin 14 through the upper or lower frame 10.11 at an appropriate position on the upper or lower edge. A slotted hole 16 is provided on the side of the frame for fastening, and the pivot pin or guide pin can be easily inserted by inserting it into the square hole 13 and fixing it with screws. performs its function.

Here, the structure of the pivot pin will be explained in detail.

The upper pivot pin 5 and the lower pivot pin 6 have different structures.

As shown in FIGS. 2 and 3, the lower pivot pin 6 has round holes 20 and 21 on the upper and lower sides 18 and 19 of a rectangular box-shaped base 17, and a long hole 22 on the side wall. The lower end is female threaded between the upper and lower round holes 20 and 21, and a locking pin 23 is inserted in the middle, and a pin 14 with a spring 24 inserted therein is inserted through the hole. A nut 25 and a pin cap 26 are fitted.

As described above, this type of structure is attached to the pin attachment part 12 provided on the lower frame of the door plate 3, and the floor rail 2
After fitting it into the lower pivot hole 27 of the pin receiver fixed to the pin holder, it can function as a pivot pin by turning the pin 14 into the lower pivot hole 27 and adjusting the entrance and exit of the pin 14 to adjust the height of the door plate 3 appropriately. .

The upper pivot pin i is one of the features of this invention,
It has a structure as shown in FIGS. 4 and 5, which is the same structure as that used for the upper and lower force field pins 7.8.

Therefore, the upper pivot pin and the upper and lower guide pins can be used in common.

Its structure consists of round holes 29.3 on the upper and lower sides of a long U-shaped base 28.
0 and has a locking part 31 on its side surface g-32
A pin 35 is inserted between the round holes 29 and 30, and the pin 35 is supported by a temporary fixing pin 33 and an externally inserted spring 34 and has a pin cap 37 on its tip.

After fixing the structure like this to the pin attachment part 12 of the upper frame 10 of the door plate 3 with machine screws 36, the ceiling rail 1
Fix the door plate by pointing the pin cap 37 toward the upper pivot hole 38 of the pin holder fixed to the pin holder. When the pin 35 is pinched and turned, the temporary fixing pin 33 comes off from the temporary fixing piece 32 and is released by the pushing force of the spring 34 as shown in FIG. It protrudes upward as shown by the two-dot chain line in the middle and fits into the upper pivot hole 38.

As mentioned above, the upper pivot pin 5 having the structure shown in FIGS. 4 and 5 can also be used as the upper guide pin 7 and the lower guide pin 8 in FIG. A feature of the present invention is that it can be installed in the form of an assembly.

In other words, if you have one piece with the structure of the lower pivot pin 6 and three pieces with the structure of the upper pivot pin 5,
This is because it is possible to meet the needs of both left-handed and right-handed folding doors without changing the door panel.

As detailed above, the pivot pin and guide pin are not integrated with the door plate, but a pin attachment part is provided on the door plate, and the pivot pin and guide pin are provided as separate parts and installed at each home etc. during assembly. Due to this structure, the entire device can be provided at a low cost, and in the event of a failure, it can be easily repaired by simply replacing the pivot pin or guide pin, and the pin does not protrude from the door plate, making it easy to pack. be.

In addition, even if the work area is very small when installing a folding door, the pivot pin and guide pin can be installed by simply tightening screws, making it easy to work, and it can easily accommodate requests for left-hand or right-hand use. It is possible.
